如何爲iOS7構建OpenCV 2.4.8？

Question

我試着讓我的EyeTracking系統再次運行。我知道已經有一些問題涉及同一問題（How to compile OpenCV for iOS7 (arm64)），但沒有任何對我有用。 github上的最新版本已經集成了所有的arm64架構。所以我不必更改python build_framwork.py。但是，隨着對OpenCV的文件框架（http://docs.opencv.org/doc/tutorials/introduction/ios_install/ios_install.html#ios-installation）構建指令帶來了在終端以下錯誤：

有人能告訴我，我怎麼能解決這個問題還是什麼問題？

sh: cmake: command not found 

該項目使用cmake來構建，它是一個命令行工具。作爲Xcode 5工具的一部分，cmake不包含在Mac OS X中 - 您需要自行安裝它。 http://www.cmake.org/cmake/resources/software.html
